Sporting a cut above a slightly swollen and red left eye, Mears appeared Monday on Fox Sports 1's RaceHub and said he had a "real good conversation" with Ambrose.

"It was a few things on the track," Mears said. "At the end of the day, none of that should ever happen. But in the heat of the moment, when you get out of your race car, and some stuff just happened to you that you didn't like, we started going at each other, and before we knew it, it escalated very quickly.

"For a moment, I kind of wanted to hit him. I thought, 'I can't do that.' So I grabbed him. It turned out the way that it did. Unfortunately, I ended up getting hit out of the deal. Marcos and I talked through it (Monday). Things happen. You get upset. We're a couple of guys who are passionate about what we do. I was on the downside of it, but I think we both got our point across and understand where we're at now."

Asked if things were OK between them, Mears said, "I think so, for the most part. You never forget getting hit, but for the most part, yeah."

The Germain Racing driver said he didn't know whether to expect any punishment from NASCAR.

"The only thing is if there isn't (a penalty) in some way, I don't know how to distinguish what I'm able to do next time in that same scenario," Mears said. "At the end of the day, if this is just him and I on the street, we already had the conversation. It's OK. But professionally, I want to know where that line is a little bit. It's hard to say what (NASCAR) will do, but either way, we're going racing next week.
